NOVAR 2600 Operating Manual
The beginning of the PFC alarm setup group main level screen is displayed on Fig. 4.11. You can
scroll through all the alarms and check their main setup and actual state. In each row there is shown :
• alarm mark … for example the U<< means voltage loss alarm
• preset control quantity limit (in any) … control quantity value threshold; for example 20% of
appropriate nominal value
• alarm indication and actuation setting and actual state …

= neither indication nor
actuation processed (switched off); I = indication is processed (set on); A = actuation is
processed; inverse I or A means that the appropriate alarm function is currently active
For details of any alarm, enter into sublevel with the  button. For example, you see the overvoltage
alarm ( U> ) setting on the picture below.
Fig. 4.12 : PFC Alarm Setup – “U>” Alarm Details
In the particular detailed alarm setup screens you can edit individual setup parameters. Excluding the
main parameters described above, there may be set in addition :
• control quantity … if a quantity size alarm event type, you can mostly select if the actual
value ( U
LN
, for the alarm example discussed ) of the quantity or corresponding average value
( U
LNAVG
, see description in the meter block part of this manual ) is used for the alarm
condition evaluation
•
delay … minimum duration of continuous alarm condition occurrence before the alarm state
gets active. With certain exceptions that applies for both activation and deactivation.
Alarm indication can be set (

) or switched off (

). For most of the alarms you can set the
actuation too – for a better overview of the alarm state, the alarm indication is usually set too
automatically.
Overview of all of alarms is shown in tab. 4.3.
Alarm actuation usually causes disconnection (step-by-step ) of all of affected compensation sections,
including the fixed ones. Due to this the controller gets into standby state. Exceptions of this rule are
listed in individual alarm overview below.
4.3.3.1 Standard Type Alarms
Standard type alarms are controlled by appropriate control quantity – you can usually choose either
actual value or averaged value (for the quantities description, see the meter block chapter further
below).
Then you can set the quantity limit and the alarm reaction delay; it is mostly valid for both activation
and deactivation.
The standard type alarms are :
• U< … undervoltage alarm
• U> … overvoltage alarm
• I< … undercurrent alarm
•
I>
… overcurrent alarm
• CHL > … CHL limit exceeded alarm
